You only need to start coding in the GSoC period (23 May onwards) but you
can begin work on it now to get a head start if you wish. Right now you
should try to get a better feel for the task ahead. So yes I advise you
look more into bool.c:
--
e.g. bool_eval does not need to be implemented with that growable dynamic
stack.
I did a patch which precompiled the CSG operator and solids scenegraph tree
into a postfix linear tree (#417) which you can find here:
https://sourceforge.net/p/brlcad/patches/417/
You can get an idea of how it works by looking at the patch. The patch is
incomplete and has some issues. It is also currently CPU only written in C.

As for the dynamic linked lists in the boolean weaving part of the code
this online presentation might be interesting:

A good primitive to start with would be ETO. Then you can do PART later.
